VAT Input Tax Apportionment in the UAE

2025-11-09 · 4 min read · By Aureus Worldwide

If your business makes both taxable and exempt supplies, you cannot simply recover all your input VAT. You must apportion it, recovering the part attributable to taxable activity and bearing the rest. For businesses with significant exempt income, apportionment is one of the most financially important VAT calculations they perform, and the method choice can move real money.

Why apportionment exists

VAT recovery is allowed on costs used to make taxable supplies, not exempt ones. Many businesses, though, incur costs that serve both, general overheads like premises, IT and administration. The rules under Federal Decree-Law No. 8 on VAT therefore require these shared costs to be split, so you recover only the taxable-related portion. Without apportionment, a partly exempt business would over-recover; with it, recovery fairly reflects how costs are used. Our input VAT recovery guide covers the underlying recovery conditions.

The three-step structure

Apportionment follows a clear sequence:

The skill is in maximising direct attribution before reaching step three. The more input VAT you can tie directly to taxable or exempt supplies, the less you leave to the blunter residual calculation, and the more accurate (and often more favourable) your recovery.

Apportionment is not just a formula on the leftover VAT. The biggest gains usually come from carefully attributing costs directly first, so the residual pot you apportion is as small and accurate as possible.

The standard method

For the residual input VAT, the standard method is generally based on the ratio of taxable supplies to total supplies:

• Calculate the value of taxable supplies as a proportion of total supplies.
• Apply that percentage to the residual input VAT to find the recoverable amount.

This values-based ratio is simple and works well for many businesses. It is applied during the year on a provisional basis, then trued up at year-end through the annual adjustment.

When a special method applies

The standard ratio does not always fairly reflect how costs are used. A business whose exempt activity consumes few overheads relative to its turnover, or the reverse, may find a values-based split distorts recovery. In such cases, a special method that better reflects actual use (for example based on headcount, floor space, or transaction counts) may be more appropriate. A special method is subject to the rules and generally requires FTA approval, so it cannot simply be adopted unilaterally. Where the amounts are significant and the standard method clearly misrepresents usage, exploring a special method with the FTA can be worthwhile.

Who needs to take this seriously

Apportionment matters most to businesses with substantial exempt income:

• Financial services, much of their output is exempt; recovery hinges on apportionment.
• Insurance, composite insurers split taxable general and exempt life business.
• Real estate, residential (often exempt) versus commercial (often taxable).
• Mixed-activity businesses, any organisation combining taxable and exempt streams.

For these businesses, the apportionment percentage applies across a large cost base, so even small changes are material. A fully taxable business, by contrast, generally recovers in full and never reaches apportionment.

The annual adjustment

Because in-year apportionment is provisional, it must be trued up once the full year is known. The annual adjustment recalculates recovery using the complete year's figures and corrects the difference. This prevents a quarter with an unusual mix from distorting the year and ensures recovery reflects the genuine annual position. Our dedicated VAT annual adjustment guide explains the calculation in detail.

Practical handling

1. Attribute directly wherever possible to reduce the residual pot.
2. Apply the standard method to residual input VAT in-year.
3. Assess whether a special method better reflects use, and seek approval if so.
4. Document the method and the basis for any direct attribution.
5. Perform the annual adjustment to true up the year.

Strong records are essential: every attribution and every method choice must be defensible if the FTA reviews your recovery.

Common apportionment pitfalls

• Under-attributing costs directly and over-relying on the ratio
• Using the standard method where it clearly distorts usage
• Adopting a special method without approval
• Forgetting the annual adjustment
• Weak documentation behind attributions and method choice
• Treating an unusual quarter as the year's position
